Out of these 3 options news paperis the best not play sand. Any sand regular, play, calcium sand or any loose substrate in general can be bad for bearded dragons. They can cause impaction in your bearded dragon, when bearded dragons eat or explore it's quite common for the substrate to get into their mouths by them diving for food (especially babies ) or when they lick around while exploring. So even feeding them out of the cage is still not safe. You should use either reptile carpet, paper towels, news paper or tile for your bearded dragons cage. In the wild bearded dragons don't even live on sand and if they do happen to be in a place with sand it is very compacted and stuck together not loose like how regular sand is. I suggest the creator of this quiz does a little more research on beardies
